John O'Boyle/The Star-LedgerMark Sanchez was back on the practice field with the Jets on Wednesday but was not yet named the starter for Sunday's game.

Perhaps engaging in a bit of gamesmanship, coach Rex Ryan refused to name his starting quarterback after today's practice although most players seem certain it'll be rookie Mark Sanchez.

Sanchez, who sprained his right knee Dec. 3 against the Bills, split the reps with veteran Kellen Clemens. He looked sharp in the portion of practice open to the media and even sharper thereafter, according to several players. He showed no signs of his injury during practice and was bouncing around the locker room afterwards, upbeat and smiling.

"It was a good practice today for Mark," said Ryan. "We'll see how Mark feels as of tomorrow morning. He looked good. He felt good. (But) he hasn't worked like that for a while.

"I want to make sure there's no swelling, make sure he feels good. That he got through the night and there were no surprises."

Ryan said it's more of a medical decision than whether or not Sanchez can physically play.
